Hello, During last SATTOSE together with Stéphane and Johan Brichau we worked on Alien FFI. Now it loads again into Pharo. Summary: a. Removed most of the "library" behavior from Alien, so now the libraries are reified: AlienLibrary and its subclasses. b. We moved the examples in Alien class to an AlienExamples class. c. Moved the libC related methods and glu code to the LibCLibrary class ( take a look at the qsort and printf methods). To load Alien framework you should: 1. place the external plugin IA32ABI in the proper folder 2. load the AlienLoader package from the Alien project in squeaksource. 3. Evaluate "AlienLoader loadInPharo " To test that it was succesfuly installed, you can do the following: 1. Evaluate AlienLoader loadLibC 2. Run the test AlienExamplesTest>> testLibCPrintf Any comments, or advice is appreciated. Fernando pd: The main problem with Alien loading into lastes Pharo was that the Alien and UnsafeAlien are added to the specialObjectsArray, and the size of it was modified since Alien package was originally published by John. pd2: Still didn't try out the AlienLoader>>loadWin32, cause i have a mac. Will try to do it in the next week.
